Abstract: The Rufous Casiornis, Casiornis rufus (Vielliot, We present nine records based on our observations car- 1916), is widespread in central South America, reaching ried out in three sites in the municipality of Uruguaiana, its southernmost distribution in northern Argentina in the western sector of Rio Grande do Sul. and . Here we present the first nine records The Rufous Casiornis was initially observed in the of the species for Rio Grande do Sul state, southern riparian of the Arroio Touro Passo (29°43′08″ S, Brazil. The records were documented with photographs 056°40′33″ W), on 9 January 2013, when a single individual and consisted mostly of lone individuals observed in was observed and photographed (Oliveira 2013a). In this riparian inserted in a matrix of grasslands and same site, the species was also recorded on four other rice fields. The Rufous Casiornis apparently occurs in occasions: 2 February 2013, 23 June 2013, 12 November very low densities in the region. More observations 2014 (Oliveira 2014b) and 14 November 2014 (Oliveira are needed to elucidate its status of occurrence in Rio 2014a). Another record, presumably corresponding to Grande do Sul. a distinct individual, was obtained on 22 July 2013 in the riparian forest of the Rio Uruguay (Oliveira 2013b; Key words: Rufous Casiornis, burlisto castaño, 29°30′04″ S, 056°49′44″ W). On 30 September 2013, an maria ‑ferrugem, geographical range individual was heard calling in the riparian forest of the Arroio Pindaí (29°43′54″ S, 056°42′13″ W). This was attracted with playback and photographed (Ritter The Rufous Casiornis, Casiornis rufus (Vielliot, 1916), is 2013) (Figure 1). Previous records in this site were also widespread in central South America, occurring from obtained on 16 January 2013 and 2 July 2013.
